Bios not detecting sata

Hello, hope someone can help with this....Upgraded my OS to Win 7 from XP but into a SATA drive while the XP was in EIDE. That was successlul after I jumpered the SATA300 to SATA150 but when I go to the Bios to make it (SATA) my first boot drive, there is no choice for it in the drop down menu....I can only see the EIDE drives there, and so can't choose Sata to boot first. I have the Asus Socket939 A8V mobo with the latest bios (0229). I want to have My SATA as the boot drive and keep the EIDE as a storage drive. I've tried several things including unplugging the EIDE drive but then the system just tells me there is no master boot drive to boot from. Please help me out here....Thank you.

Appears to me that there are no Win 7 drivers for that board...but that has nothing to do with the BIOS.

FWIW: There are any number of boards with the A8V designation at the Asus website...you need to be sure you installed the correct BIOS update.

Hi Louis, thanks for answering my post. I am positive I instaled the correct BIOS update. At start up I will see the IEDE drives and the SATA drive detection but once I go into BIOS, then I can't find it anywhere.
Just want to be able to use it as my system drive and have the EIDE's as storage.

in BIOS under Advanced --> Onboard Devices --> onchip SATA boot ROM (enabled) , save , reboot

Thanks Caperdog, but that has been enabled from the begining, even tried disabling it and then reenabling it, just in case it would help....it did not.
